Primary Outcome Measures

Name	Time	Method
The primary endpoint was defined as the changes of VO2/WR among the ischemia and control (non-ischemia) groups. The cardiopulmonary tests were scheduled before and within 3 months after (within 3 months) of the percutaneous coronary intervention.

Secondary Outcome Measures

Name	Time	Method
The secondary endpoint was defined as the changes of VO2, VCO2, AT, Peak VO2, T1/2, VO2/HR, R, VE/VO2, VE/VCO2, and VE vs. VCO2 slope among the ischemia and control (non-ischemia) groups. The cardiopulmonary tests were scheduled before and after (within 3 months) of the percutaneous coronary intervention.
